In order to clarify the purpose, technical proposal and advantages of the present disclosure, the embodiments of the present disclosure will be described in more detail with reference to the drawings below.

The principle of image display of the TFT-LCD is as follows, that is, a voltage is applied to the common electrode plate on the color film substrate and the pixel electrodes on the array substrate, respectively, and between the common electrode plate and the pixel electrodes. By controlling the magnitude of the formed electric field, the deflection angle of the liquid crystal molecule is controlled, and the amount of light transmitted is controlled to realize the display.

In a related technique, the TFT of each pixel unit is located at the intersection of the gate line and the data line, the source electrode of the TFT is connected to the data line, the gate is connected to the gate line, and the drain is connected to the pixel electrode. .. In each pixel unit, a common electrode lead wire region (pad) is provided in the common electrode wire, a storage capacitor is formed by the common electrode lead wire region and the drain of the TFT of the pixel unit, and the common electrode lead is passed through the common electrode wire. After changing the voltage loaded in the line region, the magnitude of the electric field formed between the pixel electrode and the common electrode plate can be changed. When displaying an image, it is necessary to perform different brightness control for each pixel unit in order to realize a change in screen color. The higher the brightness level, the finer the displayed image.

However, in the related technology, since each pixel unit includes only one pixel electrode, the twist angle of the liquid crystal molecules is the same for the liquid crystal molecules of the same pixel unit when displaying an image, whereby the twist angle of the liquid crystal molecules is the same. The brightness level is low and the definition of the display screen is low.

An embodiment of the present disclosure provides a display device, the display device comprising an array substrate, the array substrate comprising a plurality of pixel units, each pixel unit having a first subpixel and a second subpixel of the same color. The first sub-pixel includes a first pixel electrode and a first common electrode, and the second sub-pixel includes a second pixel electrode and a second common electrode.

Here, in the first stage, the potential difference between the first pixel electrode and the first common electrode is larger than the potential difference between the second pixel electrode and the second common electrode.

In the embodiment of the present disclosure, the common electrode included in each sub-pixel may refer to a common electrode lead wire region (pad) connected to the common electrode wire, and is also referred to as a common electrode lead wire block. The common electrode may be one electrode plate for forming a storage capacitor in a sub-pixel, for example, the common electrode may form a storage capacitor together with a second electrode of a TFT in a sub-pixel or a pixel electrode. Good. Therefore, by changing the voltage of the common electrode in the sub-pixel, the voltage of the pixel electrode in the sub-pixel can be changed, and the potential difference between the pixel electrode and the common electrode plate can be changed. That is, when the potential difference between the pixel electrode and the common electrode changes for each sub-pixel, the potential difference between the pixel electrode and the common electrode plate on the color film substrate also changes, and the twist angle of the liquid crystal molecule also changes. Finally, the grayscale displayed by the sub-pixels is changed.

In the embodiment of the present disclosure, the data voltage finally loaded by each pixel unit into the liquid crystal molecule may be equal to the average value of the two potential differences. If the adjustment particle size (that is, the minimum adjustment unit) of the potential difference between the pixel electrode and the common electrode in each sub-pixel is a, the potential difference between the pixel electrodes of the two sub-pixels and the common electrode in each sub-pixel unit is not equal. The adjustment particle size of the average value of the potential differences between the two sub-pixels can be reduced to a / 2. As a result, fine adjustment with respect to the brightness of each pixel unit can be realized, the change level of the brightness of the pixel unit can be enriched, and the definition of the display screen can be improved.

For example, in each sub-pixel, the adjustment particle size of the potential difference between the pixel electrode and the common electrode is 1 V (volt), and in the first sub pixel, the potential difference between the first pixel electrode and the first common electrode is 3 V, and the second sub Assuming that the potential difference between the second pixel electrode and the second common electrode in the pixel is 2V, the data voltage that each pixel unit finally loads into the liquid crystal molecule can be 2.5V. From the above, it was found that the adjustment particle size of the data voltage was reduced to 0.5V, and fine adjustment with respect to the brightness of the pixel unit was realized.

Similarly, it was found that the grayscale actually displayed by each pixel unit may be the average value of the grayscale displayed by the two sub-pixels, and the adjustment grain size of the gray scale of each sub-pixel is b. If there is, if the potential difference between the pixel electrodes of the two sub-pixels and the common electrode is not equal, the gray scales displayed by the two sub-pixels are not equal, and at this time, the gray scale displayed by the two sub-pixels is The adjustment grain size of the average value can be reduced to b / 2. For example, at present, the grayscale adjustment particle size of each pixel unit is generally 1, but the drive device according to the embodiment of the present disclosure can reduce the grayscale adjustment particle size of each pixel unit to 0.5. As a result, fine adjustment with respect to the brightness of each pixel unit can be realized, and the fineness of the display screen can be improved.

In the second stage, the range of the potential difference between the first pixel electrode and the first common electrode is (Vs, Vg], and Vg is gray displayed by the sub-pixel. It is the voltage required when the scale is the maximum grayscale, that is, the maximum grayscale voltage when the display device performs the display.

Illustratively, in the embodiments of the present disclosure, the range of the first grayscale is (0, P / 2], the range of the second grayscale is (P / 2, P], and P is. The maximum grayscale when the display device performs the display. Assuming that the maximum grayscale of the display device is 255, the range of the first grayscale is (0, 127.5] and the second gray. The range of scales can be (127.5, 255].

As an option, the first sub-pixel can further include a first TFT, a first data line, and a first gate line.

Illustratively, the first gate line in the first sub-pixel and the second gate line in the second sub-pixel may be two different gate lines.

Illustratively, the first gate line and the second gate line may be the same gate line, and the first data line and the second data line may be two different data lines.

Illustratively, the first common electrode in the first sub-pixel and the second common electrode in the second sub-pixel have opposite voltage polarities and / or the first common electrode and the second in the first sub-pixel. The absolute value of the voltage is not equal to that of the second common electrode in the sub-pixel. That is, the polarities of the voltages of the first common electrode in the first sub-pixel and the second common electrode in the second sub-pixel may be opposite to each other. The absolute values of the voltages of the first common electrode in the first sub-pixel and the second common electrode in the second sub-pixel may not be equal. The first common electrode in the first sub-pixel and the second common electrode in the second sub-pixel have opposite voltage polarities, and the first common electrode in the first sub-pixel and the second common electrode in the second sub-pixel May mean that the absolute values of the voltages are not equal.

This is the average value of the gray scale. Since the adjustment particle size of the average value is smaller than the grayscale adjustment particle size of each sub-pixel, finer particle size adjustment with respect to the average value can be realized by adjusting the potential difference between the pixel electrode and the common electrode of each sub-pixel. , The change level of the brightness of each pixel unit can be enriched, and the definition of the display screen can be improved.

Then, since the potential difference between the pixel electrode of the same pixel unit and the common electrode is different and the twist angle of the liquid crystal molecules of different pixels is different for the liquid crystal molecules of the same pixel unit, the change particle size of the average twist angle of the liquid crystal molecules in the same pixel unit. Becomes finer. As a result, the brightness level of the same pixel unit can be increased, and the definition of the display screen can be improved.

That is, each pixel unit in the display device includes n sub-pixels of the same color, where n ≧ 2. That is, the plurality of pixel units in the display device may be divided into a plurality of groups, and the pixel units of each group may include a plurality of adjacent pixel units of different colors. For example, each group of pixel units can include a red pixel unit, a green pixel unit, and a blue pixel unit, where each pixel unit has two sub-pixels of the same color (ie, n = 2). Can be included.

In the embodiments of the present disclosure, the first pole of the TFT is the source and the second pole of the TFT is the drain.

A storage capacitor is formed by the second electrode of the TFT in the same display area as the common electrode line in each display area. For example, in each sub-pixel, the common electrode wire 03 may be provided with a common electrode lead wire region such as the common electrode lead wire regions 081 and 082. The common electrode lead wire region forms a storage capacitor together with the second electrode of the TFT in the same display region, and in the embodiment of the present disclosure, the common electrode lead wire region is also referred to as a common electrode. With reference to FIG. 1, it can be seen that a plurality of common electrode lead wire regions are connected to each common electrode wire 03. The orthographic projection of the array substrate of each via hole 09 onto the base substrate may be located within the orthographic projection of one common lead region onto the base substrate. Of course, the orthogonal projection of the via hole 09 onto the base substrate does not have to overlap with the orthogonal projection of the common lead wire region onto the base substrate, and the embodiments of the present disclosure are not limited to this.

Of course, the storage capacitor of each sub-pixel is not limited to the storage capacitor formed by the second pole of the TFT in the same display region as the common electrode wire, and the storage capacitor may be formed in another form, for example. The common electrode lead may form a storage capacitor with the pixel electrodes in the same display area, or the common electrode lead and the pixel electrode may form a storage capacitor with the second pole of the TFT in the same display area.

In the embodiments of the present disclosure, the sub-pixels include pixel electrodes, and a plurality of pixel electrodes belonging to the same pixel unit may be located in the same column or in the same row. Each pixel unit is exemplifiedly used to emit light of one color, such as red, blue, or green light. That is, the plurality of sub-pixels included in each pixel unit may be sub-pixels of the same color, and may be, for example, red sub-pixels, green sub-pixels, or blue sub-pixels.

FIG. 1 schematically shows that each pixel unit includes two sub-pixels, a first sub-pixel and a second sub-pixel. Here, the first sub-pixel includes a first pixel electrode 061, a first TFT071, a first common electrode 081, a first data line, and a first gate line. The second sub-pixel includes a second pixel electrode 062, a second TFT072, a second common electrode 082, a second data line, and a second gate line.

Here, the first pole of the first TFT071 is connected to the first data line, the second pole of the first TFT071 is connected to the first pixel electrode 061, and the gate of the first TFT071 is connected to the first gate line.

The first pole of the second TFT072 is connected to the second data line, the second pole of the second TFT072 is connected to the second pixel electrode 062, and the gate of the second TFT072 is connected to the second gate line. The first sub-pixel further includes a first common electrode line, and the first common electrode 081 may be connected to the first common electrode line. The second sub-pixel may further include a second common electrode line, and the second common electrode 082 may be connected to the second common electrode line.

The first sub-pixel and the second sub-pixel satisfy at least one of the following conditions, that is,
The first common electrode line and the second common electrode line are two different common electrode lines.
The first data line and the second data line are two different data lines.
The first gate line and the second gate line are two different gate lines.

Illustratively, the second common electrode line and the first common electrode line are two different common electrode lines. For example, as shown in FIG. 1, the first pixel unit in the array substrate includes a first sub-pixel located in the first row and the first column, and a second sub-pixel located in the second row and the first column. Can be included. The first common electrode line of the first sub-pixel is the first common electrode line 03 from the top, and the second common electrode line of the second sub-pixel is the second common electrode line 03 from the top. The common electrode lines of the sub-pixels are different common electrode lines.

Illustratively, the first data line in the first sub-pixel and the second data line in the second sub-pixel may be the same data line, and the first gate line in the first sub-pixel and the second data line in the second sub-pixel may be the same. The two gate lines may be the same gate line. That is, referring to FIG. 1, the first pole of the first TFT071 and the first pole of the second TFT072 can be connected to the same data line 02, and the gate of the first TFT071 and the gate of the second TFT072 are connected to the same gate line 04. Can be done.

In the embodiment of the present disclosure, the voltage of the data line and the voltage of the common electrode line are superimposed, and as shown in FIG. 1, the potential difference between the first pixel electrode 061 and the first common electrode 081 and the second pixel electrode 062 The potential difference from the second common electrode 082 is set to be different. Since the potential difference between the first pixel electrode 061 and the first common electrode 081 and the potential difference between the second pixel electrode 062 and the second common electrode 082 are different, the twist angle of the liquid crystal molecules in the first sub-pixel and the twist angle in the second sub-pixel The twist angle of the liquid crystal molecules is different, and thus the twist angle of some liquid crystal molecules in each pixel unit is different from the twist angle of some other liquid crystal molecules. As a result, the change particle size of the average twist angle of the liquid crystal molecules in each pixel unit can be reduced, so that the brightness level of the pixel unit is increased and the definition of the displayed image is improved.

It can be understood that the pixel unit actually displays the mixed light effect of the first sub-pixel and the second sub-pixel, that is, the grayscale p0 actually displayed by the pixel unit is determined by the first sub-pixel. It is half the sum of the displayed grayscale p1 and the grayscale p2 displayed by the second subpixel, that is, p0 satisfies p0 = (p1 + p2) / 2.

In the first stage, the potential difference between the first pixel electrode 061 and the first common electrode 081 is larger than the potential difference between the second pixel electrode 062 and the second common electrode 082.

As one of the options, in the first stage, even if the voltage of the first common electrode 081 is smaller than the voltage of the second common electrode 082 and the voltage of the first pixel electrode 061 is equal to the voltage of the second pixel electrode 062. Good. As a result, the potential difference between the first pixel electrode 061 and the first common electrode 081 may be larger than the potential difference between the second pixel electrode 062 and the second common electrode 082.

As one of the options, in the second stage, the potential difference between the first pixel electrode 061 and the first common electrode 081 may be equal to or greater than the potential difference between the second pixel electrode 062 and the second common electrode 082.

Here, the first stage may be a stage of displaying the first gray scale, the second stage may be a stage of displaying the second gray scale, and the first gray scale is , Smaller than the second grayscale. Since the gray scale displayed by each pixel unit is determined according to the screen actually displayed by the display device, the stage at which each pixel unit is located is also determined according to the screen actually displayed.

Illustratively, the range of the first grayscale may be (0, P / 2], the range of the second grayscale may be (P / 2, P], where P is the display. The maximum grayscale when the device performs the display.

In the embodiment of the present disclosure, the potential difference V1 between the first pixel electrode 061 and the first common electrode 081 and the potential difference between the second pixel electrode and the second common electrode 082 for either the first step or the second step. The difference from V2 can be flexibly adjusted, and it is sufficient to guarantee that the average value of the gray scales of the two sub-pixels is the gray scale actually displayed by the pixel unit.

Illustratively, in the first stage of displaying the first grayscale, the data voltage Vd of the pixel unit corresponding to the actually displayed screen satisfies Vd ≦ Vs. Vs is the voltage required when the grayscale displayed by the sub-pixels is half of the maximum grayscale. Then, in the first stage, the potential difference between the first pixel electrode 061 and the first common electrode 081 is Vg or less, and the Vg is the maximum grayscale voltage when the display device performs display. At this time, the potential difference between the second pixel electrode 062 and the second common electrode 082 may be less than Vs. For example, the potential difference between the second pixel electrode 062 and the second common electrode 082 may be 0, and at this time, only the first sub-pixel emits light and the second sub-pixel does not emit light.

In the second stage of displaying the second gray scale, the data voltage Vd of the pixel unit corresponding to the actually displayed screen satisfies Vd> Vs. Then, in the second step, the potential difference V1 between the first pixel electrode 061 and the first common electrode 081 may be equal to Vg. Illustratively, Vg may be equal to 8V. At this time, the first sub-pixel displays the maximum brightness, that is, the maximum gray level p. As can be seen from the equation of grayscale p0 actually displayed by the pixel unit described above: p0 = (p1 + p2) / 2, the grayscale p2 displayed by the second sub-pixel should be p2 = 2p0-p. is there. Therefore, at this time, the potential difference V2 between the second pixel electrode 062 and the second common electrode 082 may be a voltage required when the displayed gray scale is p2.

In the second stage, since the gray scale p0 actually displayed by the pixel unit is p0> P / 2, P2 is also larger than 0, so that the potential difference between the second pixel electrode 062 and the second common electrode 082 is Greater than 0. That is, in the second stage, both the first sub-pixel and the second sub-pixel emit light.

Illustratively, assuming that the potential difference between the pixel electrode and the common electrode is 6V, the liquid crystal is completely deflected, i.e. the maximum grayscale voltage Vg = 6V. In the first stage, referring to FIG. 2, there are seven data lines 02, four common electrode lines 03, and three gate lines 04, and the data loaded into the seven data lines from left to right. The signal voltages are 3V, -3V, 3V, -3V, 3V, -3V, and 3V, respectively. The voltages of the common electrode signals loaded on the four common electrode wires from top to bottom are -3V, + 3V, -3V, and + 3V, respectively.

The 11th pole of the 1st TFT and the 1st pole of the 2nd TFT of the 1st pixel unit XS1 are both connected to the 1st data line from the left, and the gate of the 1st TFT and the gate of the 2nd TFT are both the 1st from the top. It is assumed that the first common electrode 081 is connected to the first common electrode wire 03 from the top, and the second common electrode 082 is connected to the second common electrode wire 03 from the top. As can be seen from FIG. 2, the voltage of the data signal loaded on the first data line from the left is 3V, and the voltage of the common electrode signal loaded on the first common electrode line 03 from the top is -3V. Yes, the voltage of the common electrode signal loaded on the second common electrode line 03 from the top is 3V.

Regarding the first pixel unit XS1, the potential difference V1 between the first pixel electrode 061 and the first common electrode 081 in the first sub-pixel of the pixel unit XS1 is 3- (-3) = 6V, and the second The potential difference V2 between the second pixel electrode 062 and the second common electrode 082 in the sub-pixel is 3- (+3) = 0V. At this time, the gray scale actually displayed by the pixel unit XS1 is half of the gray scale corresponding to 6V (that is, the maximum gray scale p) and the gray scale corresponding to 0V (that is, the minimum gray scale 0). That is, at this time, the gray scale displayed by the pixel unit XS1 is P / 2.

As can be seen from the above, in the first stage, the potential difference between the first pixel electrode and the first common electrode is larger than the potential difference between the second pixel electrode and the second common electrode, and the two potential differences are different. Similarly, since the potential difference between the first pixel electrode and the first common electrode in the remaining pixel units is different from the potential difference between the second pixel electrode and the second common electrode, the brightness level of each pixel unit is increased.

As one of the options, the common electrode voltage of the first sub-pixel (that is, the voltage of the first common electrode) and the common electrode voltage of the second sub-pixel (that is, the voltage of the second common electrode) have opposite polarities. Absolute values are equal.

When the voltage polarities of the two common electrodes in the same pixel unit are opposite, the data line connected to the pixel unit can realize a large potential difference only by supplying a data signal with a small voltage, whereby the array. The power consumption of the substrate can be reduced. For example, if the voltage of the first common electrode is 3V and the voltage of the second common electrode is -3V, the data line only supplies a data signal whose voltage alternates between 3V and -3V. The potential difference between the pixel electrode of one subpixel and the common electrode can be set to 6V.

As one of the options, in the first stage, the potential difference V1 between the first pixel electrode and the first common electrode of the first sub-pixel may be the voltage required when the displayed gray level is 2p0. , The potential difference V2 between the second pixel electrode of the second sub-pixel and the second common electrode may be equal to 0, that is, the gray scale displayed by the second sub-pixel may be 0. That is, the gray scale p0 actually displayed by the pixel unit is p0 = (2p0 + 0) / 2 = p0.

When entering the first stage to the second stage, for example, when the data voltage of the pixel unit corresponding to the actually displayed image changes from Vd ≦ Vs to Vd> Vs, one of the adjacent common electrode lines The voltage of the common electrode signal loaded on the common electrode line can be maintained at V0, and the voltage of the data signal loaded on the data line can be determined according to the maximum grayscale voltage Vg. The voltage of the data signal may be Vg + V0, that is, the potential difference of one sub-pixel in the pixel unit is Vg, and the gray scale p1 displayed by the sub-pixel is the maximum gray scale p. The voltage of the common electrode signal loaded on the other common electrode line can be determined according to the grayscale p0 actually displayed by the pixel unit. From the formula of grayscale p0 actually displayed by the pixel unit: p0 = (p1 + p2) / 2, it can be estimated that the grayscale displayed by the other sub-pixel must satisfy p2 = 2p0-p. it can. Therefore, the voltage of the common electrode signal loaded on the other common electrode line may be Vg + V0-Vp, where Vp is the voltage required when the displayed grayscale is p2, i.e. the other. The potential difference of the sub-pixels is Vp.

For example, assuming that the grayscale displayed by a sub-pixel linearly correlates with the potential difference of the sub-pixel (that is, the potential difference between the pixel electrode and the common electrode), that is, Vd satisfies Vd = (V1 + V2) / 2. V2 satisfies V2 = 2Vd−Vg. From this, it can be estimated that the voltage of the common electrode signal loaded on the other common electrode line is Vg + V0- (2Vd-Vg) = 2Vg-2Vd + V0. When Vg = 8V and Vd = 6V, the voltage of the common electrode signal loaded on the first common electrode line is maintained at V0 = -3V, and the voltage of the data signal loaded on the data line is 8+ (-3). = 5V, and the voltage of the common electrode signal loaded on the second common electrode line is 2 × 8-2 × 6 + (-3) = 1V. That is, the voltages of the common electrode signals loaded on the four common electrode wires from top to bottom are -3V, + 1V, -3V, and + 1V, respectively. Regarding the first pixel unit XS1, the potential difference between the first pixel electrode and the first common electrode in the first sub pixel of the pixel unit XS1 is 5- (-3) = 8V, and the second sub pixel has a potential difference of 5 (-3) = 8V. The potential difference between the second pixel electrode and the second common electrode is 5- (+1) = 4V.

In charging the first pixel unit XS1, it takes time for the potential difference between the first pixel electrode and the first common electrode to reach a predetermined Vg = 8V. In this process, the potential difference between the first pixel electrode and the first common electrode is larger than the potential difference between the second pixel electrode and the second common electrode. After the potential difference between the first pixel electrode and the first common electrode reaches Vg, the potential difference between the second pixel electrode and the second common electrode of the second sub-pixel is (2Vd-Vg). In this way, the pixel unit displays Vd = (Vg + (2Vd−Vg)) / 2. That is, the first sub-pixel can be charged to the maximum gray scale, and the second sub-pixel can be charged according to the data voltage Vd of the screen actually displayed. Similarly, since the potential difference between the first pixel electrode and the first common electrode in the remaining pixel units is different from the potential difference between the second pixel electrode and the second common electrode, the brightness level of each pixel unit is increased.

As one of the options, the polarities of the data lines of adjacent pixel units are opposite. That is, the polarities of the voltages of the data signals loaded on the data lines connected to the adjacent pixel units are opposite. For example, in the structure shown in FIG. 2, the voltage of the data signal loaded on the first data line from the left is 3V, and the voltage of the data signal loaded on the second data line is -3V.

As an option, the first sub-pixels in two adjacent columns or two rows share one common electrode line, or the second sub-pixels in two adjacent columns or two rows One common electrode wire is shared. For example, when two common electrodes of the same pixel unit are in the same column, the sub-pixels in two adjacent columns can share one common electrode line, that is, multiple sub-pixels in the same row. One common electrode wire can be shared. When two common electrodes of the same pixel unit are in the same row, sub-pixels in two adjacent rows can share one common electrode line, i.e., multiple sub-pixels in the same column are one. Common electrode wire can be shared. As a result, each sub-pixel of the same pixel unit corresponds to a different common electrode line, and it becomes easy to independently adjust the potential difference between the pixel electrode and the common electrode of each sub-pixel.

As one of the options, at least one of the voltages of the common electrode signal loaded on the first common electrode line and the second common electrode line changes periodically in the first step and the second step. For example, the voltage of the common electrode signal loaded on the first common electrode line is -3V in the first stage, 3V in the second stage, or the voltage of the common electrode signal loaded on the second common electrode line. The voltage is 3V in the first stage and 2V in the second stage.

As one of the options, the difference between the absolute value of the voltage of the common electrode signal loaded on the first common electrode line and the absolute value of the voltage of the common electrode signal loaded on the second common electrode line is the first step and It does not have to be equal in the second stage. For example, in the first stage, the difference between the absolute values of the voltages of the common electrode signals loaded on the first common electrode line and the second common electrode line may be 6V, and in the second stage, the first common electrode line may be different. The difference between the absolute value of the voltage of the common electrode signal loaded on the second common electrode line and the second common electrode line may be 4V.

As one of the options, in the first stage, the range of the difference between the potential difference between the first pixel electrode and the first common electrode and the potential difference between the second pixel electrode and the second common electrode is (0, Vg] or ( 0, Vc]. Here, Vc is the voltage required when the gray scale displayed by the sub-pixels is 2p0, and p0 is the gray scale actually displayed by the pixel unit, for example. , Vg = 8V, and in the first stage, the potential difference between the first pixel electrode and the first common electrode is 4V, the potential difference between the second pixel electrode and the second common electrode is 0V, and 2 The difference between the two potential differences is 4V, which is smaller than Vg.

As one of the options, the range of the difference between the potential difference between the first pixel electrode and the first common electrode and the potential difference between the second pixel electrode and the second common electrode is [2, Vg], and Vg is 8V. Assuming that they are equal, for example, the difference between the potential difference between the first pixel electrode and the first common electrode and the potential difference between the second pixel electrode and the second common electrode may be Vs, or the first pixel electrode. The potential difference between the electrode and the first common electrode is 1.5 to 4 times the potential difference between the second pixel electrode and the second common electrode. For example, in the first stage, the potential difference between the first pixel electrode and the first common electrode is 6V, the potential difference between the second pixel electrode and the second common electrode is 1.5V, and the potential difference between the first pixel electrode and the first common electrode is 1.5V. The potential difference from the common electrode is four times the potential difference between the second pixel electrode and the second common electrode.

As one of the options, in the second stage of displaying the second gray scale, the data voltage Vd of the pixel unit corresponding to the actually displayed screen satisfies Vd> Vs. The range of the potential difference between the first pixel electrode and the first common electrode is (Vs, Vg], and the range of the potential difference between the second pixel electrode and the second common electrode is (Vs, Vg] or (0, Vp]. Vp is the voltage required when the grayscale displayed by the sub-pixels is 2p0-p.

That is, when displaying the second gray scale, both the first sub-pixel and the second sub-pixel emit light, and the pixel unit actually displays the mixed light effect of the first sub-pixel and the second sub-pixel. To do. As one of the options, in the second step, the potential difference V1 between the first pixel electrode and the first common electrode may be equal to the potential difference V2 between the second pixel electrode and the second common electrode, and at this time, 2 The range of the potential difference between the two sub-pixels is (Vs, Vg], or the potential difference V1 between the first pixel electrode and the first common electrode may be Vg, that is, displayed by the first sub-pixel. The gray scale obtained is p, and at this time, the potential difference V2 between the second pixel electrode and the second common electrode is Vp.

Of course, in the embodiments of the present disclosure, there may only be a first step.

For example, referring to FIG. 2, there are four common electrode lines 03 and three gate lines 04, and the voltages of the data signals loaded on the seven data lines from left to right are 3V and −, respectively. 3V, 3V, -3V, 3V, -3V, 3V. The voltages of the common electrode signals loaded on the four common electrode wires from top to bottom are -3V, 1V, -3V, and 1V, respectively. Regarding the first pixel unit XS1, the potential difference between the first pixel electrode and the first common electrode in the first sub pixel of the pixel unit XS1 is 3- (-3) = 6V, and the second sub pixel has a potential difference of 3 (-3) = 6V. The potential difference between the second pixel electrode and the second common electrode is 3- (1) = 2V. The potential difference between the first pixel electrode and the first common electrode is larger than the potential difference between the second pixel electrode and the second common electrode, and the two potential differences are different. Similarly, since the potential difference between the first pixel electrode and the first common electrode in the remaining pixel units is different from the potential difference between the second pixel electrode and the second common electrode, the brightness level of each pixel unit is increased.

Illustratively, FIG. 3 is a schematic configuration diagram of an array substrate of another display device according to an embodiment of the present disclosure. The array substrate has a dual data line structure, and the pixel unit included in the array substrate can include two sub-pixels, a first sub-pixel and a second sub-pixel. As shown in FIG. 3, the first sub-pixel includes the first pixel electrode 061, the first TFT071, the first common electrode 081, the first data line, and the first gate line, and the second sub-pixel is the second pixel. Includes electrode 062, second TFT072, second common electrode 082, second data line, and second gate line.

Here, the first pole of the first TFT071 is connected to the first data line, the second pole of the first TFT071 is connected to the first pixel electrode 061, and the gate of the first TFT071 is connected to the first gate line.

The first sub-pixel further includes a first common electrode line, and the second sub-pixel further includes a second common electrode line. The first common electrode 081 may be connected to the first common electrode wire, and the second common electrode 082 may be connected to the second common electrode wire. Illustratively, the second common electrode line and the first common electrode line are two different common electrode lines.

Illustratively, the first data line in the first sub-pixel and the second data line in the second sub-pixel may be two different data lines, in the first gate line and the second sub-pixel in the first sub-pixel. The second gate line may be the same gate line. That is, the first pole of the first TFT071 and the first pole of the second TFT072 can be connected to different data lines 02, and the first TFT071 and the second TFT072 are located between the first data line and the second data line. To do. The gate of the first TFT071 and the gate of the second TFT072 can be connected to the same gate line 04.

In the first stage, the potential difference between the first pixel electrode 061 and the first common electrode is larger than the potential difference between the second pixel electrode 062 and the second common electrode.

As one of the options, in the second stage, the potential difference between the first pixel electrode 061 and the first common electrode may be greater than or equal to the potential difference between the second pixel electrode 062 and the second common electrode.

For example, in the first stage, the range of the potential difference between the first pixel electrode 061 and the first common electrode is (0, Vs]. In the second stage, the potential difference between the first pixel electrode 061 and the first common electrode The range may be (Vs, Vg], and the range of the potential difference between the second pixel electrode and the second common electrode may be (Vs, Vg].

Illustratively, it is assumed that the maximum grayscale voltage when the display performs the display is a 256-bit grayscale voltage, and in the first stage, a grayscale screen with a grayscale of 0 to 127, i.e. Vd ≤ Vs. When the above is realized, the data signal can be loaded only on the first data line, and thus the voltage signal can be supplied to the first pixel electrode 061. Alternatively, the data signal can be loaded into the first data line and the second data line at the same time, and thus the first pixel electrode 061 and the second pixel electrode 062 can be charged. At this time, the range of the potential difference V1 between the first pixel electrode 061 and the first common electrode 081 may be (0, Vc] or (0, Vg]. Here, the second pixel electrode 062 and the second common electrode are common. When the potential difference V2 with the electrode 082 is 0 or more, the range of the potential difference V1 between the first pixel electrode 061 and the first common electrode may be (0, Vs], that is, with the first sub-pixel. The second sub-pixel may emit light at the same time.

In the second stage, when a grayscale screen with a grayscale of 0 to 127, that is, Vd> Vs is realized, data signals are loaded into the first data line and the second data line, respectively, and thus via the first data line. A voltage signal can be supplied to the first pixel electrode, and the range of the potential difference between the first pixel electrode 061 and the first common electrode 081 is (Vs, Vg]. The second pixel via the second data line. By supplying a voltage signal to the electrodes, the corresponding grayscale screen display can be realized in the pixel unit. For example, the potential difference V1 between the first pixel electrode 061 and the first common electrode 081 can be set to V1 = Vg. The first sub-pixel realizes the display of the screen with the maximum brightness, that is, displays the maximum gray scale p. The potential difference V2 between the second pixel electrode 062 and the second common electrode 082 is set to a gray scale of 2p0-p. The voltage required for display and the gray scale displayed by the second sub-pixel is 2p0-p. In this way, the gray scale p0 actually displayed by the pixel unit is p0 = (p + 2p0-p). ) / 2 = p0.

At this time, by adjusting the voltage of the data signal loaded on the two data lines, the potential difference between the first pixel electrode and the first common electrode is equal to or greater than the voltage difference between the second pixel electrode and the second common electrode. Can be

Assuming that Vs = 4V, for example, in the first stage, the potential difference between the first pixel electrode and the first common electrode is 4V, and the potential difference between the second pixel electrode and the second common electrode is 0V. The difference between the two potential differences is 4V.

As one of the options, the potential difference between the first pixel electrode and the first common electrode is 1.5 to 4 times the potential difference between the second pixel electrode and the second common electrode. For example, in the first stage, the potential difference between the first pixel electrode and the first common electrode is 6V, the potential difference between the second pixel electrode and the second common electrode is 1.5V, and the potential difference between the first pixel electrode and the first common electrode is 1.5V. The potential difference from the common electrode is four times the potential difference between the second pixel electrode and the second common electrode.

Illustratively, FIG. 4 is a schematic configuration diagram of an array substrate of another display device according to an embodiment of the present disclosure. The array substrate has a dual gate line structure, and the pixel unit included in the array substrate can include two sub-pixels, a first sub-pixel and a second sub-pixel. As shown in FIG. 4, the first sub-pixel includes the first pixel electrode 061, the first TFT071, the first common electrode 081, the first data line, and the first gate line, and the second sub-pixel is the second pixel. Includes electrode 062, second TFT072, second common electrode 082, second data line, and second gate line.

Here, the first pole of the first TFT071 is connected to the first data line, the second pole of the first TFT071 is connected to the first pixel electrode 061, and the gate of the first TFT071 is connected to the first gate line.

The first pole of the second TFT072 is connected to the second data line, the second pole of the second TFT072 is connected to the second pixel electrode 062, and the gate of the second TFT072 is connected to the second gate line. The first sub-pixel further includes a first common electrode line, and the second sub-pixel further includes a second common electrode line. The first common electrode 081 may be connected to the first common electrode wire, and the second common electrode 082 may be connected to the second common electrode wire. Illustratively, the second common electrode line and the first common electrode line are two different common electrode lines.

Illustratively, the first data line in the first sub-pixel and the second data line in the second sub-pixel may be the same data line, and the first gate line in the first sub-pixel and the second data line in the second sub-pixel may be the same. The gate line may be two different gate lines, the first gate line is adjacent to the second gate line, i.e. the first gate line and the second gate are the first pixel electrode 061 and the second pixel electrode 062.

As one of the options, in the second stage, the potential difference between the first pixel electrode 061 and the first common electrode may be greater than or equal to the potential difference between the second pixel electrode 062 and the second common electrode.

Illustratively, in the first stage, when a grayscale image with a grayscale of 0 to 127 is realized, the first gate scan signal is loaded into the first gate line during the first scan period, and thus the first gate line. By loading the first gate scanning signal into the gate of the TFT 071 of the first sub-pixel via the above, the TFT 071 is turned on. The first data line supplies a voltage signal to the first pixel electrode 061 so that the potential difference between the first pixel electrode 061 and the first common electrode 081 becomes Vc. At this time, if the voltage of the second common electrode 082 is 0, the second gate line of the second sub-pixel may be closed, and the second data line cannot charge the second pixel electrode 062. The potential difference between the two sub-pixels corresponds to 0, that is, the potential difference between the second pixel electrode and the second common electrode is zero. Alternatively, if the voltage of the second common electrode 082 is not 0, the second data line becomes the second by loading the second gate scanning signal into the second gate line and loading the data signal into the second data line. The voltage of the two-pixel electrode 062 can be charged so as to be equal to the voltage of the second common electrode 082, and at this time, the potential difference between the second pixel electrode and the second common electrode is 0.

When the potential difference between the first pixel electrode 061 and the first common electrode 081 is Vc and the potential difference between the second pixel electrode and the second common electrode is 0, the gray scale displayed by the first sub-pixel is 2p0.

Further, during the first scanning period, by supplying a voltage signal to the first pixel electrode via the first data line, the voltage of the first pixel electrode is the maximum grayscale voltage Vg, and the first sub-pixel has the maximum brightness. The screen display is realized, that is, the gray scale displayed by the first sub-pixel is the maximum gray scale p. By supplying a voltage signal to the second pixel electrode via the second data line during the second scanning period, the potential difference between the second pixel electrode and the second common electrode is displayed in grayscale. It is the voltage required when it is 2p0-p, that is, the grayscale displayed by the first sub-pixel is 2p0-p, whereby the pixel unit realizes the display of the corresponding grayscale p0 screen. it can.

The voltage of the first common electrode may be equal, that is, the voltage of the first common electrode is equal to the voltage of the second common electrode. At this time, by turning on the two gate wires in different scanning periods, different voltages can be loaded on the first pixel electrode and the second pixel electrode, and thus the first pixel electrode and the first common electrode can be loaded. The potential difference is greater than or equal to the voltage difference between the second pixel electrode and the second common electrode.

As one of the options, in the second stage, the potential difference between the first pixel electrode 061 and the first common electrode may be greater than or equal to the potential difference between the second pixel electrode 062 and the second common electrode.

As one of the options, at least one of the voltages of the common electrode signal loaded on the first common electrode line and the second common electrode line changes periodically in the first step and the second step. For example, the voltage of the common electrode signal loaded on the first common electrode line is -3V in the first stage, 3V in the second stage, or the voltage of the common electrode signal loaded on the second common electrode line. The voltage is 3V in the first stage and 2V in the second stage.

As one of the options, the difference between the absolute value of the voltage of the common electrode signal loaded on the first common electrode line and the absolute value of the voltage of the common electrode signal loaded on the second common electrode line is the first step and It does not have to be equal in the second stage.

The gray scales are also different, and the gray scales actually displayed by each pixel unit are the average values of the gray scales displayed by the first sub-pixel and the second sub-pixel. Since the adjustment particle size of the average value is smaller than the grayscale adjustment particle size of each sub-pixel, finer particle size adjustment with respect to the average value can be realized by adjusting the potential difference between the pixel electrode and the common electrode of each sub-pixel. , The change level of the brightness of each pixel unit can be enriched, and the definition of the display screen can be improved.

Then, since the potential difference between the pixel electrode of the same pixel unit and the common electrode is different and the twist angle of the liquid crystal molecules of different pixels is different for the liquid crystal molecules of the same pixel unit, the change particle size of the average twist angle of the liquid crystal molecules in the same pixel unit.

Becomes finer. As a result, the brightness level of the same pixel unit can be increased, and the definition of the display screen can be improved.

The embodiments of the present disclosure provide another method of driving a display device, which display device may be the display device shown in FIGS. 1, 2, or 4. As shown in FIG. 6, the method can include the following steps.

It may be smaller than the second gray scale.

As one of the options, the voltage polarity of the common electrode signal loaded on the first common electrode and the second common electrode is opposite, and / or the common electrode loaded on the first common electrode and the second common electrode. The absolute values of the signal voltages are not equal.

Illustratively, as shown in FIG. 3, the first data line in the first sub-pixel and the second data line in the second sub-pixel are two different data lines, and the data signal is correspondingly the first data line. And loading into the second data line can include:

That is, the data signal is loaded on the first data line and the second data line in the same period.

Then, the first gate line in the first sub-pixel and the second gate line in the second sub-pixel may be the same gate line, and after loading the gate drive signal into the gate line, the TFT in the first sub-pixel And the TFTs in the second sub-pixel can be turned on at the same time, the first data line can charge the first pixel electrode, and the second data line can charge the second pixel electrode, so that the first of the same pixel unit The pixel electrode and the second pixel electrode are simultaneously charged via different data lines.

As one of the options, the voltages of the data signals loaded on the first data line and the second data line may be different or the same. For example, when the voltage of the first common electrode is equal to the voltage of the second common electrode, the first data line and the first data line are used to ensure that the potential difference of the first sub-pixel and the potential difference of the second sub-pixel are not equal. 2 The voltage of the data signal loaded on the data line can be different. When the voltage of the first common electrode and the voltage of the second common electrode are not equal, the voltage of the data signal loaded on the first data line and the second data line may be the same, thereby and the potential difference of the first subpixel. It can also be guaranteed that the potential differences of the second subpixels are not equal.

As another selectable embodiment, during the first scan period of the first stage, the first gate scan signal may be loaded only on the first gate line and the signal may not be loaded on the second gate line. At this time, the first data line can charge the first pixel electrode. During the second scanning period of the first stage, the second gate scanning signal may be loaded only on the second gate line and the signal may not be loaded on the first gate line. At this time, the second data line can charge the second pixel electrode. As a result, the first pixel electrode and the second pixel electrode can be charged in different scanning periods via different gate lines.

During the second scanning period of the second stage, the second gate scanning signal may be loaded only on the second gate line and the signal may not be loaded on the first gate line.

By charging the second pixel electrode during the second scanning period, the potential difference between the second pixel electrode and the second common electrode is set to the voltage Vp required when the displayed gray scale is p2 = 2p0-p. The gray scale displayed by the second sub-pixel can be 2p0-p.

As one of the options, at least one of the voltages of the common electrode signal loaded on the first common electrode line and the second common electrode line changes periodically in the first step and the second step.

The voltage is 3V in the first stage and 2V in the second stage.

As one of the options, the difference between the absolute value of the voltage of the common electrode signal loaded on the first common electrode line and the absolute value of the voltage of the common electrode signal loaded on the second common electrode line is the first step and It does not have to be equal in the second stage.

When the potential difference between the second pixel electrode 062 and the second common electrode 082 is 0 or more. At a certain time, the range of the potential difference between the first pixel electrode 061 and the first common electrode may be (0, Vs], that is, the first sub-pixel and the second sub-pixel may emit light at the same time. ..

Assuming that Vg is equal to 8V, for example, in the first stage, the potential difference between the first pixel electrode and the first common electrode is 4V, and the potential difference between the second pixel electrode and the second common electrode is 0V. The difference between the two potential differences is 4V, which is smaller than Vg.

As one of the options, the potential difference between the first pixel electrode and the first common electrode is 1.5 to 4 times the potential difference between the second pixel electrode and the second common electrode. For example, in the first stage, the potential difference between the first pixel electrode and the first common electrode is 6V, the potential difference between the second pixel electrode and the second common electrode is 1.5V, and the potential difference between the first pixel electrode and the first common electrode is 1.5V. The potential difference from the common electrode is four times the potential difference between the second pixel electrode and the second common electrode.

As one of the options, in the second stage, the data voltage Vd of the pixel unit corresponding to the actually displayed screen is the range of the potential difference between the second pixel electrode and the second common electrode when Vd> Vs is satisfied. Is (Vs, Vg] or (0, Vp]. Vp is the voltage required when the grayscale displayed by the sub-pixels is 2p0-p.

By loading on the common electrode, the potential difference between the first pixel electrode and the first common electrode becomes larger than the potential difference between the second pixel electrode and the second common electrode, and the first sub-pixel 1 and the first sub-pixel of the same pixel unit become larger. The gray scale displayed by the two sub-pixels is also different, and the gray scale actually displayed by each pixel unit is the average value of the gray scale displayed by the first sub-pixel and the second sub-pixel. Since the adjustment particle size of the average value is smaller than the grayscale adjustment particle size of each sub-pixel, finer particle size adjustment with respect to the average value can be realized by adjusting the potential difference between the pixel electrode and the common electrode of each sub-pixel. , The change level of the brightness of each pixel unit can be enriched, and the definition of the display screen can be improved.
